Question 282100
(2,4) and (-3,-6)
Y=mX+b m=slope & b= the Y intercept.
m=(Y2-Y1)/(X2-X1)=(-6-4)/(-3-2)=-10/-5=2
4=2*2+b
4=4+b
b=4-4
b=0 the Y intercept.
Y=2X IS THE LINE EQUATION.
PROOF:
{{{ graph( 200, 200, -10, 10, -10, 10, y = 2x) }}} (graph 200x200 pixels, x from -10 to 10, y from -10 to 10, y = 2x).
